A light-element radioactive ion-beam capability has been developed at the LBNL 88-Inch Cyclotron. The system is based on the coupled-cyclotrons method and utilizes short-lived species, e.g., {sup 11}C , {sup 14}O , {sup 13}N produced by (p, n) and (p, {alpha}) reactions at the LBNL Biomedical Isotope Facility Cyclotron. In a first experiment, {sup 197}Au({sup 11}C, xn){sup 208-} {sup x}At excitation functions have been measured for energies ranging from the Coulomb barrier up to 110 MeV using a beam of {sup 11}C with intensities up to (1-2)x10{sup 8} ions/sec on target. The results of this experiment are compared to measurements of {sup 197}Au({sup 12}C, xn){sup 209-} {sup x}At excitation functions. (c) 2000 The American Physical Society.
